The nervous system is your body's control center, processing information and coordinating responses through electrical and chemical signals.
Watch how neural signals travel through different pathways, from simple reflexes that bypass the brain entirely to complex voluntary movements that require conscious thought.
This interactive simulation lets you explore how neural signals travel through a realistic human nervous system. Here's how to get the most out of it:
Normal Activity: Baseline neural activity - good starting point
Reflex Response: Watch spinal reflexes bypass the brain entirely
Voluntary Movement: See how conscious decisions travel from brain to muscles
Sensory Processing: Follow sensory information from body to brain
Stress Response: Rapid, intense signaling throughout the system
Sleep State: Slow delta waves and reduced activity
Learning Mode: Pathway reinforcement through repeated signals
Pain Response: Fast and slow pain signals via different nerve types
Memory Recall: Complex brain network activation patterns
Fight/Flight: Massive sympathetic nervous system activation
For Reflexes: Focus on spinal cord, use slower signal speed
For Brain Activity: Zoom into brain regions, try learning or memory modes
For Pain Signals: Follow peripheral nerves to brain, note different speeds
For Motor Control: Start with brain focus, follow signals to periphery
For Overview: Use center view with normal activity mode
